2 Claims.

i used. Further objects are to provide a machine of compact size, which will occupy small floor space in proportion to its capacity, which can be operated at a low cost and which can be manufactured and sold at a relatively low price.

These and other objects and advantages will be readily understood from the following description and from the accompanying drawing of a preferred embodiment in which, however, certain modifications may be made without depart- 1 ing from the scope of the appended claims. In

the drawing Fig. 1 is a front elevation shown with parts broken away and partly in cross section,

Fig. 2 a top view, and

Fig. 3 an end View.

Referring to all the views, simultaneously, the machine consists of a stand, formed of four uprights 10, on the upper part of which are mounted a plurality of compartments 11. A single compartment 12 is mounted on the lower part of the stand in such a manner that a space 13 is formed between this compartment and the upper one. Each of the upper compartments contains a hat block 14 which is rotatingly mounted and ver- 1 tically supported in a bearing 15. The hat block is demountable from its shaft so that the blocks may be varied in shapes and sizes as required. The blocks are provided with skirts 16 to keep sizing out of the bearings 15. Either solid or wire j hat blocks may be used.

The hat block is mounted on the upper end of a vertical shaft 17 which is driven by a motor 18 by means of a pair of bevel discs 19. A slanting cam 20, which is notched at both its upper and jits lower limit, is located under an operating handle 21. When this handle is turned in one direction the shaft is lowered and the bevel discs engage; when turned in the opposite direction the shaft is lifted and the bevel discs disengage.

lThe notches on the cam limit the movement of the handle and prevent accidental turning. The

handles and cams are contained in the space 13,

while the motors and the bevel discs are mounted inside the lower cabinet.

An electric heater, consisting of a resistance element 22 held in grooves in a refractory annular ring 23, is mounted on a support 24 under each of the upper compartments. Each heater is so located that its center opening is concentric with the vertical shaft 17, and the opening is of sufficient size to prevent undue heating of the shaft on the bearings in which they rotate. Each heater is provided with an independent switch 25, mounted on the front of the lower cabinet. The motors are likewise connected independently.

A tank 26 is mounted on the end of the machine by a pair of hooks 27 which engage over the edge of the adjacent upper compartment. This tank is also provided with an electric heater 28 which is connected by a conductor wire 29 to an outlet 30 attached on the front of the lower cabinet. A similar outlet 31 is provided at the other end of the machine for use when a tank is attached to that end. The tank is preferably constructed with legs 32 which extend below the heater so that it may be placed on these legs when not suspended on the machine.

In addition to the operating handle 21, a treadle 34 is provided for starting and stopping the rotations of each of the hat blocks. Each of these treadles, which are hinged below the compartment 12 as shown at 35 in Fig. 3, are connected to a lever 36 by a link 37. The lever 36 is hinged at 38 and a conical pivot 39, which engages in a seat in the end of shaft 17, is secured on the upper side of the lever. A tension spring 40 holds the pivot in contact with the seat in the shaft. By operating the treadle the shaft 17 may be lowered so as to cause the bevel discs 19 to engage and thus rotate the hat block.

The machine is employed in the following manner. The hat to be sized is dipped in the proper sizing contained in the tank 26; the sizing being kept at the p'roper temperature by the electric heater mounted under the tank. After the hat is Withdrawn from the tank it is placed on one of the hat blocks in one of the upper compartments and the handle 21 is turned, or the treadle 34 depressed, so that the block will rotate. The rotation of the hat causes all the excess sizing to be thrown off by centrifugal force. The sizing, as it is thrown off, is caught in the compartment in which the hat block is contained.

To prevent the sizing from adhering to the walls and bottoms of the compartments the electric heaters are employed. These heaters impart just sufiicient heat to the walls and bottoms to maintain the sizing in a liquid state so that it will flow down the walls, over the bottoms, and out through the spouts 33. From here it is collected and poured back into the original container.

It will be seen that by using these heaters not only is there no waste of sizing but the compartments are kept in a clean, sanitary condition. It

ported on the upper part of the stand; a lowercompartment; an outlet formed in the upper compartment; an open space intermediate of said upper and lower compartments; a demountable hat block rotatively mounted on a vertical shaft in the upper compartment; means for rotating said vertical shaft contained in the lower compartment; manual means for starting and stopping the rotation of said vertical shaft; an electric heating element located below the upper compartment f or heating the walls and bottom of this compartment to enable any sizing deposited thereon to drain from said outlet; and the electric heating element contained in an annular base through the center of which the vertical shaft passes.

2. In a hat sizing machine of the class described; a stand; a hat sizing compartment supported on the upper part of the stand; a lower compartment; an outlet formed in the upper compartment; an open space intermediate of said upper and lower compartments; a demountable hat block rotatively mounted on a vertical shaft contained in the lower compartment; manual means for starting and stopping the rotation of said vertical shaft; an electric heating element located below the upper compartment for heating the walls and bottom of this compartment to enable any sizing deposited thereon to drain from said outlet; the electric heating element contained in an annular base through the center of which the vert' al shaft passes; and an electrically heated dipping tank having hooks engageable over the edge of the sizing compartment for supporting it on either side thereof.
